My next, and last problem with building on my cygwin

[Jim Holmlund]

The jdk CreateJars.gmk file creates a file named _the.jars.contents which contains, well you guessed 
it, a list of all the contents of a jar file.

It then greps for .class files  in this list.  The problem is that on my machine, the lines in 
_the.jars.contents end with that stupid ^M char.  This prevents  the greps from finding any .class 
files.

I don't know the best fix for this.  I made this change and now I can build thru images successfully:
